Highway 12 in the Delta, one of the primary routes from San Joaquin County to the northern Bay Area, will be shut down entirely this weekend while crews continue work on a major project to realign the road.
The closure begins at 10 p.m. Friday and runs through 5 a.m. Monday, the California Department of Transportation said.
From Stockton, Highway 4 is a good alternative to access Contra Costa and Solano counties. Farther north, motorists could take Interstate 5 to Walnut Grove Road and cut over to Highway 160, which meets up with Highway 12 just east of Rio Vista. That’s a detour of about 45 minutes.

The new highway will have full 8-foot shoulders as well as a concrete barrier in the median.
This weekend’s closure, however, is not limited to Bouldin Island. It will include all of Highway 12 between I-5 and Highway 160….
